WebProposed by Clive Granger in 1969 [1], Granger causality analysis (GCA) has been widely applied to analyze the relationships between time series. Briefly, a time series X is said to Granger-cause time series Y if the values of X provide statistically significant information about future values of Y. The GCA is very useful in functional
